WIRE-FORMING MEANS.

'Application nica January 12,v 1924. smal mi. 685,767. y

To all whom t 'may concern.' Be it known that I, BERT L. VAN ORMAN, a citizen of the United States, residingat Detroit, county of Wayne, State of Michigan, have invented certain new and useful mprovements in Wire-Forming Means, of whlch the following is a specification.

- This invention relates to improvements in machines. I have i ustrated my impi-ovements as I have embodied them in a machine -or forming double springs o r a springhaving independent coils designed for automobile brllres:

`im and yreadily" adapted springs for other piuioses. v

The main objects o my invention are: First, to provide an improved wire work.- ing machine which is.. automatic in its operation exce t in theinatter of feeding and is adapte to forma straight iece o wire into a spring having double coils.

Second, to working machine of the class described for use in forming v which Ymay be readily adjusted to the work desired- Third, to rovide a machine of the character descri which is of large capacity, easy to operate and knot likely to get Aout of re air. 15;

urther c'ibje'cts'i,` and objects pertainin to details and economies of construction an operation willv deiinitel appearfrom the detailedv description te ollow..

I accomplish the objects'of my invention by the devices andlmeans' described in the following l'speciication.' The." invention is clearly defined and Y A structurdwhic isa preferred embodimentiof my inventionfis clearly illustrated in the accompanying. drawing forminga part of this application, in whichi-v v Fig. I is a planview ofmy improved wire ceiling or sprinlg forming machine.

Fig. II isa eta' vertical section on a line corresponding to line 2-2 o'FigljI. Fig, III is a detail view, partially in vertical transverse section, on a line corresponding to line 3-3- of Fig, I. Fig. IV is a detail view mainly in vertical section on a line corresponding to line 4.-4 of Fig. I. Fig. V is a detail view on a line ce'rrerovements are, however, desirable Amay be adjusted relative to each ot parallel planes. rovide an improved wireinted out in the claims.

perspective'- view of the Fig. II is a completed work. Y Y In the drawing thel sectionalV viev's 4are taken looking in the direction of the little larrows at the ends of the 'section lines and similar numerals of reference refer to simi-v y lar parts throughout the several'views.

Referring to the drawing, the table or: 'l 4bed 1 is provided with a central longitudinal slot 2, the purpose of which will appear as the description proceeds. At either side of4 mount coiler supports 3,l these supports being' adjustably secured to the this slot bed by means of the bolts 4 engaging the 'i longitudinal slots 5 so that the supports er in Each support carries a coiler s indle 6 having a coiler head 7 thereon, e coiler spindles being provided with feed screws 8 enacting with the feed nuts 9 on the su ports sc that as. the spindles are rotated t e heads are moved laterally. Each coiler head is provided with a form core 10 reciprocatin axially through the spindle and rojectin ead, an with a coiler lug 11, the lug being grooved to retain the wire in engagement therewith. l

The spindles are driven to rotate the head and to feed the spindles axially, the driving means illustrated comprising the elongated pinions 12 on the spindles with which the driven gears 13 mesh, the driving gears 14 being connected to the gears 13 to rotate therewith. The drivin racks 15 engage these driving. gears an are connected to at the inner end of the coiler the pitman 16 on the crank gears 17 'so that*y l .the spindles are driven with a forward and return movement as the racks make 4one complete stroke.

These gears 17 'are driven from a source I; of power as the pulley '18 is lconnected through a suitable train of lgears and a clutch mechanism indicated generally at 19. This clutch mechanism is controlled by the clutch lever 20 connected by the link 21 to the foot lever 22. 4

The cam wheel 23 coacting with the roller 24 on the clutch lever (see Fig. II) is designed to hold the clutch out of engagement until the parts have made a complete cycle. As the details of the clutch form no part of this invention they are not further described herein.

The core 10 is reciprocated by means of the levers 25 pivoted at 26, the levers engaging the slots 27 at the outer ends of the cores so that the supports may be adjusted longitudinally without,affecting the operating connections. The levers 26 are connected by the links 28 to the arms 29 on they rock-shafts 30, these rock-shafts being 'also provided with arms 3l which l, are actuated by the cams 32 on the gear wheels 17, the

-cams beingv positioned so that the actuation of the core is properly timed. y

With the parts thus arranged the stock indicated at 33 is placed in the machine (see Fig V) while the coiler heads are at rest.

The operator then .engages the clutch by pressing the foot lever 22 and the machine is driven through a complete cycle which wraps the wire around the cores, and retracts the cores discharging the wire through the slot 2. This slot permits the ends of the wire to swing as they are wrapped around the cores, the heads 7 being laterally retracted as the winding progresses and the cores being returned to. the initial position at the end of the cycle.

I have illustrated my improvements as I have particularly embodied the same in a machine for forming springs having double coils. I have not attempted to illustrate or describe certain modifications or adaptations which I contemplate as I believe the disclosure made will enable those skilled in the art to embody or adapt the same as may be desired. Y

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
